Diffusion Missile
From Wikitroid, the Metroid wiki
Diffusion Missiles have a very large blast radius, but only when charged. When charged and fired, the Diffusion Missile creates a shockwave of ice energy that spans the entire screen, freezing enemies. This is only necessary once, but is useful in other situations.
They do not use up any more Missiles than would be normally used, even when charged. Whether charged or not, the Diffusion Missile is more powerful than the standard Ice Missile. An enemy that takes three Ice Missiles to kill will generally only take two Diffusion Missiles, even if Samus dosen't charge them. It is readily noticeable that the Diffusion Missile launches are much more explosive and powerful than the standard Ice Missiles, seeming to create a visual difference between the two. Once Samus gets the upgrade, the aspect of her missiles will change and they will resemble Super Metroid's Super Missiles.
